Auxiliary motors start and stop delay

Delay stabilizes the contactors before starting or stopping a

motor.

Parameter 8115 AUX MOT START D is left to its default

value 5 s. Parameter 8116 AUX MOT STOP D is left to it’s

default value 20 s.

Number of auxiliary motors and motors in total

Parameter 8117 NR OF AUX MOT is set to 2. Parameter

8127 MOTORS is set to 3.

Autochange functionality for SPFC

The Autochange functionality for SPFC equalizes duty time

between multiple motors, when auxiliary motors are not

running. The time interval between motor changes is

managed with parameter 8118.

Interlocks

Interlock detects if any of the pumps are unavailable and

starts the next available pump, when used. Set parameter

8120 INTERLOCKS to take input from DI3 in this example

(depends of the number of interlocks and how thay are

connected).

Default I/O settings

1. Hand: 0…10 V -> 0…50 Hz.

PID/PFC: 0…10 V ->

0…100% PID setpoint.

2. 360 degree grounding under

a clamp.

3. The signal source must be

powered externally. See the

manufacturer’s instructions.

Start delay for speed controlled motor

Parameter 8122 PFC START DELAY is left to its default

value 0,5 s.

Enabling pump and fan control

Parameter 8123 PFC ENABLE is set to 3 (SPFC +

AUTOCHANGE)

Relay configuration

Relay configuration depends how many and how the

motors are connected.

Note! The macro SPFC already sets Transistor output

parameter 1805 DO SIGNAL to PFC as an additional

relay output which is connected.

Parameter 1401 RELAY OUTPUT 1 is set to PFC

Parameter 1402 RELAY OUTPUT 2 is set to PFC
